Anatomically, the ear can be divided into three major sections called the outer ear, the middle ear and the inner ear. How many statements are correct for inner ear? i. The organ of Corti is a structure located on the basilar membrane which contains hair cells that act as auditory receptors. ii. A large number of processes called stereo cilia are projected from the apical part of each hair cells iii. Above the rows of the hair cells is a thin elastic membrane called tectorial membrane iv. The vestibular apparatus is composed of three semi-circular canals and the otolith organ consisting of the saccule and utricle. v. Semi-circular canals contain a projecting ridge called macula vi. The saccule and utricle contain a projecting ridge called cristae vii. The cristae and macula responsible for maintenance of balance of the body and posture.
